# Description On 64-bit platforms the current size of `Value` is 56 bytes. The limiting variants were `Closure` and `Range`. Boxing the two reduces the size of Value to 48 bytes. This is the minimal size possible with our current 16-byte `Span` and any 24-byte `Vec` container which we use in several variants. (Note the extra full 8-bytes necessary for the discriminant or other smaller values due to the 8-byte alignment of `usize`) This is leads to a size reduction of ~15% for `Value` and should overall be beneficial as both `Range` and `Closure` are rarely used compared to the primitive types or even our general container types. # User-Facing Changes Less memory used, potential runtime benefits. (Too late in the evening to run the benchmarks myself right now) |

nu-protocol
The nu-protocol crate holds the definitions of structs/traits that are used throughout Nushell. This gives us one way to expose them to many other crates, as well as make these definitions available to each other, without causing mutually recursive dependencies.
